Delve into software architecture, exploring key principles, patterns, and quality attributes. Gain insights with case studies and projects, enhancing your practical skills in system design and optimization.

Software Architecture in Applications-01.png

This course offers a deep dive into the world of software architecture. It’s designed to equip software developers and architects with the knowledge and skills necessary to create, evaluate, and optimize software systems. The course covers a range of critical topics to ensure a strong foundation in architectural principles and strategies.

You will start by exploring architectural concepts and the relationship between quality attributes, requirements, and architectural styles. You’ll also examine different architectural patterns and strategies, including centralized and decentralized architecture, layered pattern, broker pattern, and microservices. Then, you’ll go into the details of important quality attributes needed while developing an architecture.

The course is equipped with multiple case studies and two projects to further enhance learning. These real-world scenarios and hands-on projects are strategically incorporated to give learners practical insights.

Software Architecture in Applications

# Overview
**Security testing** is the vital process of evaluating the security of a system or application to reveal vulnerabilities or weaknesses that attackers could exploit. Several security tests can assess the system's security, including:

# Vulnerability scanning

**Vulnerability scanning** involves automated tools that scan a system or application for known vulnerabilities. The scanners can be set up to search for a range of vulnerabilities, such as software vulnerabilities, configuration weaknesses, and misconfigured or vulnerable services.

For instance, a vulnerability scanner can be configured to identify SQL injection vulnerabilities, cross-site scripting vulnerabilities, or insecure configurations in a web application.
 
# Penetration testing
**Penetration testing**, sometimes known as **pen testing**, is the practice of simulating an attack on a system or application in order to find vulnerabilities or flaws that automated scanners might miss. To uncover vulnerabilities, penetration testing necessitates manual testing using a number of methodologies and technologies.


An example of what a penetration tester might do is to try to gain unauthorized access to sensitive data or functionality in an application by attempting to bypass authentication or access controls, injecting malicious code, or using other methods.
 
# Security review
A **security review** is a comprehensive manual evaluation of a system or application's security controls, processes, and practices. Internal security experts or external consultants can conduct the review.

Suppose that for a company, a security review is an in-depth analysis of the system's architecture, code, configurations, security policies, procedures, and practices. This process is carried out to identify potential vulnerabilities or weaknesses in the system's security and recommend improvements.
